ok just as a follow up the compressor clutch was the problem along with a leaking seal. I put in a new compressor and receiver dryer and all new o rings for the lines. I purchased a small 3 cfm robinair pump and it pulled a nice vacuum. The vacuum held overnight so I charged it up with r134 and she's nice and cool. Spent 250 for a brand new compressor, 160 for the the vacuum pump, 35 for the dryer plus about 30 for freon and 60 for a nice set of gauges. Not too bad considering what it would cost to have someone do this.

The DTC's I originally pulled wher 419 and 421. The 419 code was accurate (compressor clutch) but anyone pulling a 421 should be aware that this refers to part n65 (pulse module)and is a false code. I cleared the dtc's and this code keeps coming back but there are no syptoms that I can tell.
